Remarks

COM Signature

From vsshell.idl:

HRESULT IVsFontAndColorEvents::OnItemChanged(
   [in] REFGUID rguidCategory,
   [in] LPCOLESTR szItem,
   [in] LONG iItem,
   [in] const ColorableItemInfo *pInfo,
   [in] COLORREF crLiteralForeground,
   [in] COLORREF crLiteralBackground
);

When the bForegroundValid, bBackgroundValid, and bFontFlagsValid flags are set to true, the corresponding Display Items settings were modified.

If the Display Items setting was not modified, then the value in these arguments will be false, and the corresponding color data is invalid and should be ignored.
